• Flow (adapted by KGI to use bootstrap modal)
  • Adding files by clicking <div class="fileuploader-input"> or dragging files into it
    1. jquery.fileuploader.js:
       • s = input element, p = parent element, o = new input element, l = list element, sl = input elements, n = options, f = fileuploader
       • f.init:
         • set p, language, merge options
         • callback n.beforeRender(parentEl p, inputEl s); Callback fired before rendering the fileuploader elements, by returning false, you will prevent the rendering
         • f.redesign();
           • set theme, set new input html, hide standard input
           • f.thumbnails.create(); create thumbnails list
             • callback n.thumbnails.beforeShow(parentEl p, newInputEl o, inputEl s); Callback fired before adding the list element
             • create box (n.thumbnails.box)
             • bind item popup, start, retry, rotate, remove/cancel methods to the selector n.thumbnails._selectors.popup_open, .start, .retry, .rotate, .remove
           • set drag&drop container
         • if (n.files) { f.files.append(n.files); } append files from options (see pre-loading files)
         • callback n.afterRender(listEl l, parentEl p, newInputEl o, inputEl s); Callback fired after rendering the fileuploader elements
           • fotos.js.afterRender:
             • bind click to .fileuploader-input –> api.open()
             • bind dropdown buttons (.fileuploader-action-settings, .gallery-action-rename, .gallery-action-asmain)
         • f.bindUnbindEvents(true) bind all events (click input –> f.onEvent, drag&drop, clipboardPaste, sorter)
         • f.reset()
           • f.files.clear() clear files from the memory
             • n.onEmpty(listEl l, parentEl p, newInputEl o, inputEl s) Callback fired when fileuploader has no files
    2. $('body').on('show.bs.modal', '#modalFotos', …) after clicking the button to show modal for a specific album
       • ajax/fileuploader.php {action: 'preload', fotoalbum_id: fotoalbumId} (see below for details)
       • api.reset(); = f.reset (see above)
       • api.append(preload) (nop if no files in album yet)
    3. click .fileuploader-input –> api.open(); –> s.trigger('click'); –> f.onEvent('click') –> nop;
       • after selecting image: f.onEvent('change') –> f.onChange.call(this) [this=input.gallery_media]
       • f.onChange
         • callback n.beforeSelect(files, listEl l, parentEl p, newInputEl o, inputEl s) Callback fired after selecting the files from computer but only before processing them; by returning false, you will prevent the processing of the files but they will remain in the input
         • for each selected file { item = f._itFl[f.files.add(file, 'choosed')] }
           • f.files.add: (id=Date.now())
